When the crane crosses over, a rotational crane on the portal crane is used for performing installation and disassembly of a walking track beam of a cart of the portal crane in a front and back manner, crossing operation can be performed conveniently and rapidly, and the auxiliary adjusting time of the crane can be shortened.
Description
Technical field
Present invention invention is related to a kind of large bridge bridge plate face laying construction equipment, belongs to hoisting machinery and manufactures and designs
Field.
Background technology
In Large Span Bridges process of construction, floorings are covered with the girder steel formula bridge such as steel arch bridge, cable-stayed bridge, suspension bridge,
Floorings weight is typically in below 40t, and overall dimensions are existing typically in long X width x height=below 12000mmx5000mmx250mm
The floorings laying construction technique of large bridge typically set up using Bridge Erector or spread using boat form crane barge in water channel
If the equipment investment of a Bridge Erector input is built, energy bed board is few within one day.Its complex process, equipment cost investment is big, and efficiency is low,
Bridge construction is long in time limit, and for more being laid using crane barge across bridge of the mountain valley without water channel, this is existing construction technology
With the subject matter existing for equipment.
The content of the invention
The present invention provide a kind of change of large bridge bridge plate face laying construction across, adapt to certain bridge deck width scope
Gantry crane.
What the present invention was realized in：
A kind of floorings lay gantry crane, including support walking door frame, bridge crane, suspender, and door frame is steel knot
Structure assembly, bridge crane is walked thereon, and its girder adopts cantilever design, and the center for making side floorings can exceed that door frame crossbeam
Center and lay side bridge plate；Bridge crane makees whole machine movement in described door frame, can adjust and take plate and bed board positioning；Door frame
A cantilever crane is respectively set on four supporting legs, before and after cantilever crane gantry crane running track is had bad luck and is laid, carry out bed board door machine
Sectional type moves ahead or retreats；Suspender includes suspension bracket, suspender axle and rope tool, and suspender adopts boatswain chair nose suspension type, can 360 full circle swingings；Rope
Tool is hung in the arc groove above suspension bracket using ears rope and shackle locking type, ears rope.
The present invention crane cross across when, by the rotating lifting being arranged on straddle truck complete gantry crane walking track girder
Before and after peace tear open, can fast and easy cross across, shorten crane auxiliary adjustment time.
Floorings of the present invention laying gantry crane is realized becoming across adapting to certain bridge deck width scope.
Description of the drawings
Fig. 1 is the total front view of gantry crane of the present invention；
Fig. 2 is the gantry crane schematic side view of the present invention；
Fig. 3 is the suspender front view of the gantry crane of the present invention
Fig. 4 is the suspender side view of the present invention;
Fig. 5 is the ears rope figure of the present invention；
It is designated in figure：The cantilever crane of 4 rail clamping device of Bridge 1 formula crane 2 door frame, 3 door frame travelling mechanism 5
The rope tool groove of 10 shackle 11 of 6 ring-chain hoist, 7 suspender, 8 suspender axle 9.
Specific embodiment
It is further described below in conjunction with the accompanying drawings：
Floorings of the present invention laying gantry crane is by supporting walking door frame 2, bridge crane 1, suspender, the design of door frame
Method using sill is raised, makes the bridge plate when the center of floorings can exceed that door frame crossbeam center and lay, in door frame
Respectively set on four supporting legs and before and after a cantilever crane 6, cantilever crane 6 gantry crane running track is had bad luck and laid, carry out bed board door
Machine sectional type moves ahead or retreats；Bridge crane on door frame carries out taking plate and bed board on door frame；Suspender adopts boatswain chair suspension bracket
Formula, can 360 full circle swingings；Rope tool 9 fast and easy hanging cable and can take rope using ears rope and shackle locking type.
Crane total figure shown in Fig. 1 is:
1. bridge crane, whole function there is not door frame to make whole machine movement, can adjust and take plate and bed board is positioned at；
2. door frame steel construction assembly, used as the main load-supporting part of bed board door machine, bridge crane is walked thereon, door
The profile of frame frame structure can meet bridge plating station requirement, for ease of bridge plate rotational positioning fall plate positioning, raise down
Crossbeam leaves the right or normal track face highly, it is determined as 1904mm;Door frame girder adopts cantilever design, makes bed board function lay the side plate of bridge；Door frame
Girder is readily transported and transition is reused using segmentation high-strength bolt connection, and limited change can be realized across using；
3. walk on stage, ladder, railing, electrical equipment is arranged thereon, as access path；
4. it is traveling mechanism of the larger traveller, its driving side is three-in-one driving, and plate paver work is used and adjusted as plate paver telephone-moving
Use position；
5. for rail clamping device is as plate paver parking Windproof safety and is having gradient pavement construction as safety device；
6. cantilever crane 6 moves forward as plate paver or retrogressing track has bad luck use, is the important Auxiliary Functioning Unit of plate paver, real
The existing advance mistake of track is across greatly shortening telephone-moving non-cutting time；
7. suspender has in design larger improvement and breakthrough as critical function part during planking operation, existing technique
Using hoist cable without suspension bracket, so whole hoisting height is higher, and equipment height is accordingly also improved, for some bridges such as steel arch bridge
Hoisting height cannot be greatly shortened using nose suspension type, multiple tracks circular arc is provided with suspension bracket body frame by lifting appliance, this suspender
Groove, to adapt to the hanging cable of the floorings of various length dimension specifications, ears rope is hung in the arc groove above suspension bracket body frame, energy
Swing, to adapt to the floorings of various width dimensions specifications, suspender has versatility and facilitates operability.
The typical operation step of floorings laying gantry crane is as follows:
Floorings lay gantry crane mounting and adjusting to normal work OFF state → in place → fortune Liangping wooden handcart transport bridge floor
Dolly on plate to gantry crane lower section → bridge crane back to floorings center of gravity top at take plate → dolly move ahead and bridge crane be displaced to peace
Holding position and become a full member floorings → and install floorings (middle plate) in place → flat car transport floorings（Side plate）On → bridge crane
Dolly retreat take side plate be forwarded to installation site and side plate of becoming a full member → crane whereabouts side plate in place → install another piece of side plate →
Track → mistake is had bad luck across → above-mentioned the course of work of repetition crane.
Former bridge floor bed board is long because of non-cutting time, can only at most lay 12 blocks of plates within one day, and an existing bed board gantry crane exists
After Xiangjiang River Bridge comes into operation, one day can 25 pieces of bed board.
As can be seen here, bed board gantry crane of the present invention is compared with original technology, with substantive distinguishing features and progress, in fact
The beneficial effect applied is also highly significant.
